BOILER CLEANER Application led March 25, 1929. Serial No. 349,821.

The invention relates to improvements in flexible blow oif pipes for boilers and has for its object to provide the flexible pipe with segmental plates, preferably welded thereto, and having apertures extending therethrough for registering with apertures or ports in the conduit cut therein after the segmental members are welded to position.

A further object is to provide the ends of the segmental member with downwardly exl' cleaner conduit formed from a flexible metallic conduit having at spaced points plates provided with ports registering with ports in the conduit and supporting lugs carried by the plates.

With the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawings, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings:

Figure 1 is a longitudinal sectional view through a conventional form of boiler, show ing the cleaner applied thereto.

Figure 2 is a horizontal sectional view through the rear end of the boiler 'taken on 5.5 line 2-2 of Figure l.

Figure 3 is an enlarged bottom plan view of the rectangular portion of the cleaner.

Figure 4 ,is a vertical transverse sectional view through the conduitk and one of the plates. f

Figure 5 is a vertical longitudinal sectional view through one of the plates and the lower side of the conduit.`

Figure 6 is a bottom perspective view of one of the plates.

Referring `to the drawings, the numeral '1 designates the horizontal portion of a conventional form of boiler, and 2 the rear downwardly extending portion thereof having the upwardly extending lire box casing 3 thereinin spaced relation whereby a rectangularlyr shaped chamber 4 is formed around the fire box casing 3. The products of combustion within the 're box 5 pass upwardly and thence through the tube 6in the usuall manner to the atmosphere through a stack not shown. It is to be understoodthat the boiler may be provided with the usual steam discharge pipe, and feed water may be supplied thereto in kany suitable manner, however for purposes of illustration a conventional form of supply pipe 7 is shown which preferably leads to a feed pump not shown. It has been found in boilers, particularly marine boilers that sediment and scale accumulate in the bottom of the boiler, and under'ordinary conditions it is knecessary to close down the boiler from time to time to clean the same,

however with the device hereinafter set forth the pressure within the boiler is utilized for forcing sediment and scale from the boiler without shutting down the boiler.

- Y The boiler cleaner comprises a exible confire box 3 and merges into the rectangular shaped portion 10 of the conduit, which is also formed from what is known as metallic 'i of boiler, therefore the cleaner can be applied to the boiler Without changing the construction thereof, and at the same time the conduit can be sold in running feet if desired for application to the boiler.

Secured to the underside of the conduit 8 and its portion 10 are segmenta-lly shaped plates 11, Which are preferably Welded at l2 to the conduit, the purpose of which Will presently appear. It will be noted that the conduit 8 is" forinedwith convolutions, and by Welding the plates 11 to the underside thereof, said convolutions Will be rigidly held when the elongated apertures 13 are cut in ception of that portion to which the plates are secured, said plate being provided With a discharge port registering With a discharge port in the secured convolutions of the conduit.

2. A boiler cleaner conduit formed from a flexible metallic pipe built up from a plurality of convolutions, a segmetal plate secured to some of the pipe convolutions to one side thereof and having an intake port registering With an vintake port in the secured convoluticns and lugs carried by the ends of the plate and extending outwardly in relation to the plate and terminating beyond the plate.

the conduit. The apertures 13 register with the ports 111 in the plates llland it Will be seen that when the discharge valve 15 is opened, the pressure .Within the boilerrwill force the sediment and dislodge scale through the ports 14: and apertures 13 with some of the Waterfrom the boiler, therefore the boil'- er will be cleaned. n

The valve 15 is carried by the discharge pipe 1 6 which may lead to any suitable source of discharge. Extending downwardly `from the sides of the port 1e are toothed flanges 18, WhichV flanges assist in breaking up the scale and sediment incident to the movement marine boiler, as it is obvious that the conduit Will flex as the boat rolls. The: conduit is maintained spaced from Athe boiler v1walls by means of lugs 19 which extend downwardly Vfrom the ends of the plates 11, therefore the discharge ports ll Will be in positions'vvhere the mud and'sca'le can be forced through the ports by the pressure Within the boiler. If so desired the cleaner conduit and its plates can 1ce-inanufactured and sold by the running foot, to be applied to different types Yof boilers, and' it is obvious that by forming the cleaner conduit from said flexible metallic conduit it Will not deteriorate and the device can be placed in the boiler and easily bent to extend around parts, so it Will not be necessary to vary theconstruction'of theboiler in applying the device thereto. 1

From the above it Will be seen that a boiler cleaner is provided Vwhich is simple in construction, and one which may be easilyand quickly applied to boilers of varying construction Without varying the construction of the boiler.

The invention having been set forth what is claimed as new and useful is Y l.
